Earth's Layers
Tectonics
Rocks!
Fossils
Weathering, Erosion, and Depostion
100
This layer is very thin and contains lots of water.
What is the crust?
100
Where volcanoes and earthquakes occur.
What are faults?
100

Type of rock created when magma cools.

What are igneous rocks?

100

Created from remains of plants and animals.

What is a fossil?

100

The breaking of rocks into sediments by wind, raind, freezing water, plant roots, etc.

What is weathering?

200
Temperatures in this layer are so hot the rocks move as if on a conveyor belt.
What is the mantle?
200
When two plates crash into eachother.
What is a convergent boundary?
200
Type of rock created when pieces of rocks and sand are compacted and cemented together.
What are sedimentary rocks?
200

You are more likely to find a fossil after it has been brought to the surface by wind or rain erosion, or even a natural disaster.

True or False?

True

200

The movement of sediment by wind or water.

What is erosion?

300
This layer contains iron and nickel so hot it is like pudding.
What is the outer core?
300
Formed when two plates move away from each other?
What is a volcano?
300
Type of rocks that are changed by heat and pressure.
What are metamorphic rocks?
300

Fossils are mostly found in these types of rocks.

What is sedimentary rocks?

300

The dropping of sediment in rivers, lakes, down hills or mountains.

What is deposition?

400
This layer is solid iron and rock.
What is the inner core?
400
Formed in the ocean at a convergent boundary.
What is a trench?
400
The system to understanding the formation of rocks is called this.
What is the Rock Cycle?
400

Older fossils can be found in upper layers of rocks.

True or False?

False

400

Reaction with chemicals, water, oxygen, and organisms causes this type of weathering.

What is chemical weathering?
500
These two things increase the further into the earth you go.
What are heat and temperature?
500
Type of boundary that causes earthquakes.
What are transform or sliding boundaries?
500
This causes the sediment to be created.
What are weathering and erosion?
500

Fossils can be found anywhere on the Earth.

True or False?

True

500

Changes from wind, water, and ice cause this type of weathering.

What is physical weathering?
